>>4155240 if someone is left eye dominant, using a rangefinder style body can be pretty annoying for them. Rangefinders almost always have bad eye relief with very flat backs, so your nose will smush into the back of the camera and potentially smudge up the screen. Maybe you're willing to compromize here because you like an OVF and you do a lot of flash photography or because you like a lagless experience. In which case you could look towards something like the X-Pro series or a Leica.
